The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here. Those having skill in the art will recognize that the state of the art has progressed to the point where there is little distinction left between hardware and software implementations of aspects of systems; the use of hardware or software is generally (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. Those having skill in the art will appreciate that there are various vehicles by which processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a mainly software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes and/or devices and/or other technologies described herein may be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary.

Further, those skilled in the art will recognize that the mechanical structures disclosed are exemplary structures and many other forms and materials may be employed in constructing such structures.

Galvanic vestibular stimulation is a method in which a stimulus current is provided to the vestibular system of the human body. This is accomplished by providing electrical contacts or otherwise providing electrical stimulation of the nerves near the vestibular site. For example, the contacts may be provided near the mastoid processes on the human head. Galvanic stimulation of the vestibular organs may be achieved by passing a small current between the mastoid processes. In some studies, it has been shown that a large galvanic body sway can be evoked by galvanic vestibular stimulation. Further, it has been shown that rocking or bobbing of the head may also be accomplished.

Further, by providing stimulation at different frequencies, patterns, and magnitudes, other movements may be achieved. In general, the vestibular system detects head movement by sensing head acceleration with specialized peripheral receptors in the inner ear that comprise semicircular canals and otolith organs. The vestibular system is important in virtually every aspect of daily life, because head acceleration information is essential for adequate behavior in three-dimensional space not only through vestibular reflexes that act constantly on somatic muscels and autonomic organs, but also through various cognitive functions such as perception of self movement. In galvanic vestibular stimulation, small-amplitude galvanic current is delivered transcutaneously or via other methods to the vestibular afferents that lie directly below the mastoid bones.

Galvanic vestibular stimulation has many uses. For example, galvanic vestibular stimulation may be used for game playing, therapy, movement training, music enjoyment, and other varied uses. Galvanic vestibular stimulation may be accomplished through, methods and structures. Such methods and structures may include different control algorithms, sensors, inputs, programs, etc. and may be applied in order to enable galvanic vestibular stimulation in an application setting. Referring now to FIG. 1, a generalized schematic of a vestibular stimulation system for a user is depicted. System 100 includes a headset 110 having earphones or earbuds 115 and a control unit 120 attached thereto. Earbuds 110 include a speaker 122, a feedback sensor 124, stimulator contacts 126, a stimulation device 128 and a current source 130. Any or all of these structures may be included in headset 110 or may be elsewhere such as in control unit 120 or associated with a computer 150 or other processing device. Control unit 120 may include control algorithms 132, user parameter settings 134, learning or adaptive algorithms 136, and a database including music and/or a score or other reference information 138. Control unit 120 may also include a communications interface 140. Communications interface 140 may be used to communicate with any of a variety of devices including but not limited to a processing device, such as a computer 150.

In use, headset 110 may be worn by a user 105. Headset 110 may include vestibular stimulator contacts 126 which may be surface electrodes, which may or may not use a contact conductive gel or other chemical placed between the skin and the electrodes. In an exemplary embodiment, it may be possible to induce or influence user motion by using any of a variety of protocols resulting in different performance. For example it may be possible to stimulate the user by using a sine wave current with a frequency in the range of 1 to 2 Hz. The amplitude of such stimulation may be in the range of a few tenths of a milliamp to a few milliamps. The stimulation may occur over a period of just a few seconds to several seconds. All of these factors depend on the performance to be achieved. Such performance may be discovered through training, modeling or through experimentation.

In accordance with an exemplary embodiment, galvanic vestibular stimulation system 100 or like systems may be used to stimulate the vestibular system of a user and cause various motional effects including, but not limited to rocking or swaying of the head, rocking or swaying of the body, induce walking or change of direction of walking, among others.
